Experts Warn Businesses To Brace For More Cyber Attacks

The security flaw that hackers used to launch the attacks Friday was made public after information was stolen from the U.S. National Security Agency, which routinely searches for flaws in software and builds tools to exploit them.

Local media reported Monday that patients arriving at Dharmais Cancer Hospital over the weekend were unable to get queue numbers and had to wait several hours while staff worked with paper records. Keeping "offline" backups of data stored in locations inaccessible to the infected computer, such as external storage drives, prevents them from being accessed by the ransomware, thus accelerating data restoration.

"We are infusing AI into every product and service we offer, from Xbox to Windows, from Bing to Office", Harry Shum, Microsoft's Executive Vice President of AI and Research said on Day 1 of the conference.

Earlier, Kaspersky researcher Costin Raiu cited 45,000 attacks in 74 countries, saying that the malware, a self-replicating "worm", was spreading quickly.

Forcepoint said in a statement that the attack had "global scope", affecting organisations in Australia, Belgium, France, Germany, Italy and Mexico.

The Financial Times reported that the list of organizations hit by WannaCry has steadily lengthened: alongside Britain's National Health Service, victims include the Deutsche Bahn, FedEx, Russia's ministry of the interior, Renault, Telefónica and China National Petroleum Corp.

"The NHS wasn't targeted", he wrote.

Critical infrastructure agencies including banks, airports, telecom networks and stock markets have been asked to take precautions to shield themselves against the crippling global ransomware attack WannaCry. But some experts have argued this attack could have been vastly mitigated if the NSA told Microsoft sooner.

Lynne Owens, director-general of Britain's National Crime Agency, said there was no indication of a second surge in the cyberattack but warned, "That doesn't mean there won't be one". Some of the victims have reportedly regained access to their files after paying, although security experts advise against complying with ransom demands.




It demands payment in three days or the price is doubled, and if none is received in seven days, the files will be deleted, according to the screen message.

Code for exploiting that bug, which is known as "Eternal Blue", was released on the internet in March by a hacking group known as the Shadow Brokers.

British media had reported a year ago that most public health organizations were using an outdated version of Microsoft Windows that was not equipped with security updates.

A global cyberattack leveraging hacking tools widely believed by researchers to have been developed by the US National Security Agency hit worldwide shipper FedEx, disrupted Britain's health system and infected computers in almost 100 countries on Friday.

In February 2016, a Los Angeles hospital, the Hollywood Presbyterian Medical Center, paid $17,000 in Bitcoin to hackers who took control of its computers for more than a week. By late morning, some people were still filling out forms manually, but the hospital said 70 percent of systems were back online.

A spokesman for Barts Health NHS Trust in London said it was experiencing "major IT disruption" and delays at all four of its hospitals.

Caroline Brennan, 41, went to the hospital to see her brother, who had open heart surgery. "However, they chose not to tell Microsoft about it. And some of them may not be well prepared for such attacks", Camacho said.
